Phyc110 Physcs Questions, which are three in number. Need to dicuss about movement of particles at various velocities among other questions. If you have any question please contact me first

Overview

 The particle moves along the positive X-axis, hence its velocity varies as V=?, where ? is a positive constant. Assuming that at the moment t=0 the particle was located at the point ?=0, please find:  how does velocity and acceleration of the particle depend on time / (time dependence of velocity and acceleration of the particl
